Abstract: Recent reports of cosmological parity violation in the 4PCF raises the question of how such violations could be systematically generated. Here we present a constructive procedure to generate arbitrary violations of vectorial and tensorial types on any scale, which is computationally efficient in the squeezed limit. We directly compute their numerical transfer function, and find strong conservation in the linear regime. This procedure spans all squeezed parity violating observables at the 4PCF, following the quadratic estimator classification.
